Dane Springmeyer 352586e9d7 handle pj_transform HUGE_VAL results (aka inf) ...

- turns out pj_transform will not always return an error code for
   failed transforms and may instead just set values as HUGE_VAL
 - this commit handles this and calls it an error by return false
   from forward/backward

Arguably if `point_count` > 1 some values might be correctly transformed
while others might be HUGE_VAL. For the purposes of Mapnik we will consider
any HUGE_VAL as an error because we have no way to handle partial failures.
